Is Your GMC Envoy Running Rough? Get Back on the Road with Confidence.
There’s nothing more frustrating than a vehicle you can’t rely on. If your 2006 GMC Envoy is suffering from a persistent check engine light, stalling, erratic shifting, or a no-start condition, a failing Powertrain Control Module (PCM) is often the culprit. This isn’t just an inconvenience; it affects your vehicle’s performance, fuel economy, and safety. Instead of spending a fortune at the dealership, get the definitive solution that restores your truck’s performance and your peace of mind.
Common Symptoms & Your Solution
A failing PCM can manifest in numerous ways. You might be experiencing one or more of the following issues:
- Check Engine Light (CEL) Illumination: Often with communication-related codes like P0601, P0602, P0606, or other controller errors.
- Engine Performance Problems: Stalling, hesitation, rough idling, misfires, or a significant loss of power.
- Poor Fuel Economy: The engine computer is critical for managing fuel delivery. A faulty one can cause your Envoy to consume much more gas than usual.
- Transmission Issues: Harsh or delayed shifting, as the PCM also controls transmission functions.
- No-Start Condition: The PCM controls the fuel and ignition systems; if it fails completely, your vehicle won’t start at all.
This pre-programmed 2006 GMC Envoy PCM is the direct answer to these problems. We take a quality, tested module and flash it with the latest official GM software, specifically matched to your vehicle’s unique 17-digit VIN. This ensures all systemsโfrom the engine and transmission to the anti-theft systemโfunction exactly as the factory intended.

An Expert’s Note on VIN Programming
Why is VIN programming so critical? In modern vehicles like your Envoy, the PCM is the central nervous system. It’s not a one-size-fits-all part. Programming it to your VIN ensures it communicates correctly with the BCM (Body Control Module), anti-theft system (GM’s Passlock), and instrument cluster. A non-programmed or incorrectly programmed module can result in a no-start condition, even if the part is perfectly functional. We handle this complex step for you, so you receive a component that is truly ready to install right out of the box. This is the key to a successful, hassle-free repair.
Don’t let a faulty computer keep your reliable SUV off the road. By installing our expertly prepared 2006 GMC Envoy PCM, you’re not just replacing a part; you’re restoring the core of your vehicle’s operational integrity. Order today and get your truck running right again.
Frequently Asked Questions
Do I need to do any programming myself?
No. This PCM arrives fully programmed to your vehicle’s VIN and is ready for installation. In some cases, a ‘Crankshaft Variation Relearn’ may be required after installation, which can be performed with a capable bi-directional scan tool.
What information do you need from me?
After you place your order, we will need your vehicle’s 17-digit Vehicle Identification Number (VIN). This is crucial for us to program the module correctly for your specific vehicle options and software.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the original PCM (e.g., codes P0601-P0606), then this part is the correct solution. It’s essential to ensure your vehicle’s issues have been properly diagnosed, as other sensors or wiring problems can also trigger a check engine light.
Is this compatible with other models besides the 2006 GMC Envoy?
Yes. This PCM is compatible with a range of 2004-2006 GM vehicles, including the Chevrolet Trailblazer, Buick Rainier, Isuzu Ascender, Chevrolet Colorado, and GMC Canyon, among others. Please verify your part number or consult the full fitment list to confirm compatibility.
How difficult is the installation?
For someone with basic mechanical skills, the installation is straightforward. It typically involves disconnecting the battery, unplugging the electrical connectors from the old PCM, unbolting it from its bracket, and then installing the new one in the reverse order. It’s located in the engine bay for easy access.
